From one of the appendices to the death certificates of the Municipality of Amsterdam, a copy of a request from May 1948 from the administrator of the Van Esso family, addressed to the registry of the District Court in Amsterdam, it appears that the three members of the Van Esso family were deported on 29 April 1943 from the Hamburgerstrasse assembly camp in Berlin to Auschwitz. The date of April 29 seems to be incorrect, because the Gedenkbuch Berlins der jüdischen Opfer des Nationalsozialismus shows that they were deported to Auschwitz on transport 37 of 19 April 1943.
On the basis of that request from May 1948, by decision of the District Court dated 12 September 1948, death certificates were drawn up by the municipality of Amsterdam, in which the death of Meijer van Esso, Marie van Esso-van Zuiden and Leo van Esso was officially established as 15 September 1943 in Auschwitz.
However, notes on their registration cards from the file cabinet of the Jewish Council, made after the war, indicate that Meijer van Esso was gassed in August 1943 according to a report R.S.T, which Marie van Esso-van Zuiden according to report R.S.T. died in May 1943 and Leo van Esso according to report R.S.T. died in September 1943.
Furthermore, the victim database of Yad Vashem has shown that Meijer van Esso, his wife Marie and son Leo stayed in Berlin during the war. The same data can also be found in the NS Documentation Center of the city of Cologne with the addition: “Letzter frei gewählter Wohnort: Berlin” which shows that the Van Esso's at some point during the war - apparently not forced - moved to Berlin. So it could happen that they were deported from the assembly camp in the Hamburgerstrasse in Berlin to Auschwitz.
